A Fall River man testified Friday that he was sitting in his car outside the complex, when he saw two men walk past him toward the vehicle parked behind him. A few seconds later, the witness said he heard a “pop” that he recognized as a gunshot.

Testimony resumed Friday in the murder trial of two men accused of killing Edward Platts at the Father Diaferio housing complex on Nov. 18, 2010.

A Fall River man testified Friday that he was sitting in his car outside the complex, when he saw two men walk past him toward the vehicle parked behind him. A few seconds later, the witness said he heard a “pop” that he recognized as a gunshot.

“It really happened so fast. There was a loud vroom, headlights and then (the vehicle) smashed into me,” said the witness, who described one of the two men he saw as possibly having long hair in a pony tail.

However, the witness was unable to identify the defendants as the men he saw that night.

Prosecutors allege that Charles Mendez, 30, formerly of Barnaby Street, shot Platts, 31, to death in his car, which then crashed into the witness’s vehicle before coming to rest against a utility pole. Platts’ car was still running and in gear when police arrived at the scene.

Prosecutors also allege that Mendez and Tacuma Massie, 31, formerly of Hope St., arranged to meet Platts, an aspiring musician, for a marijuana deal. Instead, prosecutors said, Mendez shot Platts and stole $4,200 in cash, as well as a pit bull puppy, from the victim’s vehicle. Within 15 minutes of the homicide, police arrested both suspects, who were both armed with loaded handguns, police said.

According to testimony, the defendants were accompanied by two women, who had driven them around Fall River earlier that day. A half-hour before Platts’ murder, Mendez and Massie are accused of assaulting and robbing another man at gunpoint whom they had arranged to meet for a marijuana transaction.

A young woman who has admitted to having a role in arranging the alleged marijuana deals received immunity from criminal charges in order to testify for the prosecution on Monday. The witness declined to have a court-appointed attorney represent her.

On Friday, prosecutors called upon other civilian witnesses, including a man who said he was smoking and listening to music inside his van when a vehicle rear-ended him outside the housing development. The witness said he later learned about the murder from talking to neighbors.

Testimony, which began Wednesday, will continue Monday in Fall River Superior Court. The trial is expected to last one week.
